Quality control inspection is a fundamental process that ensures products and services meet certain predetermined standards or specifications. It is crucial in import and export trade because the inspection process is to verify the quality of supplied goods and other relevant aspects of the order and sales contract.
QC inspection, performed by professionals known as Quality Controllers (QC), is a vital component of supply chain management (SCM). By implementing an effective QC system, companies can identify and address quality issues before shipping, reducing the likelihood of customer complaints and returns. This blog will now carefully illustrate the types, importance, benefits and other aspects of quality control in manufacturing for you.
Part 1. What Are Quality Control Services?
Quality control services encompass various activities conducted to ensure that products and services meet predetermined standards and specifications. These services involve inspections carried out by different entities depending on the client’s role in the supply chain.
There are three types of inspection services:
1. First-party inspection: Arranged by the manufacturer themselves.
2. Second-party inspection: Dispatched by the customer company.
3. Third-party inspection: Conducted by external inspection agencies commissioned by the customer.
Effective quality control requires a systematic approach that includes setting quality standards, developing control plans, implementing procedures, and monitoring results. Collaboration and communication among all parties involved in the supply chain, including suppliers, manufacturers, and buyers, are crucial.

Part 2. Types of Inspections in Quality Control
1. Factory Evaluation – Assessing Manufacturing Facilities
During a factory evaluation, an auditor assigns inspectors to inspect the working conditions, production status, facilities, manufacturing equipment, manufacturing methods, quality assurance management, and personnel of the production enterprise.
This evaluation is conducted according to customer requirements, and the resulting explanations and opinions are shared with the customer. The factory evaluation not only helps customers investigate potential quality accidents but also provides valuable improvement suggestions for the factory.
2. Pre-Production Inspection
Inspection personnel conduct random sampling inspections of raw materials, initial processed products, and components produced during the production process.
3. In-Line Inspection
Inspection personnel conduct inspections of semi-finished products on the production line, checking for discrepancies and deviations, reporting to the factory, and providing effective methods for correcting errors and deviations.
4. Final Inspection
Inspection personnel check the quantity, process, function, color, size specifications, packaging, and other details of the goods before delivery (generally 80% of the products are packaged after 100% of the production is completed). The sample drawn method is carried out in accordance with international standards such as ISO2859/NF X06-022/ANSI/ASQC Z1.4/BS 6001/DIN 40080 and follows the buyer’s AQL sampling level.
Part 3. What Quality Control Methods to Take
Sample Size and Acceptable Quality Level (AQL)
Inspecting 100% of the goods is the safest way to ensure quality, but it can be time-consuming and expensive for large batches. That’s why finding a balance between product quality risks and QC costs is important. This balance point is called the “sample size.”
During the sampling inspection process, QC needs to determine how many defects can be found and what level of defects can be accepted or rejected. This is known as the “acceptable quality level” (AQL).
Types of Defects in Quality Control
During the quality inspection process, defects are classified into three levels based on their severity: critical, major, and minor.
Critical defects are those that can potentially harm the human body or violate laws and regulations, such as sharp edges, corners, and electrical leakage.
Major defects are significant functional or appearance defects, such as poorly printed logos or insulation cups that do not insulate.
Minor defects are minor appearance defects like slight scratches or minor printing defects on the surface.
Experienced QC personnel can usually classify defects based on these principles. However, some customers prefer to create a Defective Classification List (DCL) to ensure that all participating QC personnel understand the defect classification. This list includes all defects related to the product and indicates the assigned defect level for each one.
Part 4. Why Is Quality Control Important in Supply Chain Management
1. Ensuring Compliance
Quality control helps you verify that the goods supplied by the supplier meet the quality requirements specified by national laws, regulations, or relevant standards. This is essential to ensure that the products meet the required safety, health, and environmental standards.
2. Preventing Delays and Defects
Timely detection and prevention of delivery delays and product defects can save you from potential losses and reputation damage. In case of any issues, emergency and remedial measures can be taken immediately to minimize the impact.
3. Reducing Consumer Complaints
